Abstract: Disclosed is a method for transmitting and receiving data between a user equipment (UE) and a base station in a narrowband wireless communication system. Specifically, the method includes transmitting, to the UE, a preconfigured uplink (UL) resource (PUR) configuration via RRC signalling, receiving, from the UE, uplink data on the PUR when the UE is in an idle mode, and transmitting, to the UE, a feedback for the uplink data, wherein the feedback is configured to be transmitted on an NPDCCH after a specific time has passed from the PUR reception.

Abstract: The present specification provides a method for transmitting uplink data by using a preset uplink resource (PUR) in a wireless communication system. More specifically, the method, which is performed by a terminal, includes: a step for receiving setting information from a base station in an RRC connected state, the setting information being for transmitting uplink data by using the PUR in an RRC idle state; a step for transitioning from the RRC connected state to the RRC idle state; and a step for using the PUR to transmit the uplink data to the base station in the RRC idle state on the basis of the setting information.

Abstract: A method for transmitting an MTC physical downlink control channel (MPDCCH) by a base station in a wireless communication system supporting machine type communication (MTC). A base station transmits, to a terminal. configuration information related to the transmission of an MPDCCH and maps the MPDCCH onto multiple resource elements (REs) of at least one first symbol constituting a first slot of a special subframe. The special subframe is a subframe in which, among symbols constituting the subframe, the number of symbols for data transmission is smaller than or equal to a predetermined number. The base station transmits the MPDCCH to the terminal over the multiple resource elements, wherein the mapping step is performed by copying at least one second symbol of a second slot adjacent to the first slot onto the at least one first symbol.

Abstract: This specification provides a method for transmitting an NPRACH preamble in a wireless communication system supporting TDD. More specifically, the method performed by the UE includes: receiving, from a base station, NPRACH configuration information including control information for a repetition number of NPRACH preambles including symbol groups through a higher layer signaling; and transmitting, to the base station, the NPRACH preamble repeatedly through frequency hopping of a symbol group based on the NPRACH configuration information, in which a frequency location of the symbol group is determined based on a first parameter related to a start subcarrier and a second parameter related to the frequency hopping.

Abstract: One embodiment of the present invention relates to a method and a device for transmitting and receiving a signal in a wireless communication system, the method comprising the steps of: performing a random access procedure; monitoring a physical downlink control channel (PDCCH) for an ON duration on the basis of a configured discontinuous reception (DRX) operation after performing the random access procedure; and operating an inactivity timer on the basis of the successfully received PDCCH for the ON duration. During the random access procedure, a random access preamble is transmitted in one or two physical random access channel (PRACH) slots. The one or two PRACH slots are determined from among N slots corresponding to a reference slot. A subcarrier spacing (SCS) setting value for the reference slot may be 2 on the basis of the SCS setting value applied to the N slots being 5 or 6.
